How to deal with sticking DOGS

My bench dog holes are drilled 3/4” round and the oak dogs are really tight, I mean have to use hammer and dowel to knock them out tight. They have the closer buttons in them and fit loose enough to finger push out until the high humity hits. It’s been raining a little every day for about a week now. Fan stays running in the shop always and the 3/4” holdfasts, while not used in the dog holes, slide in with no problem so I’m thinking that I’m getting swelling in the dogs. If I sand them down to fit good now they might me too loose when it dries some. Any ideas or is anyone dealing with similar issues?

I would sand them to fit loosely provided the buttons don’t let them slip through. In use the pressure of the clamping forces will do the rest. On my metal dogs the diameter of the dog is closer to 5/8” than 3/4”. Oh and wax the dogs and the hole with paste wax?

Starting at 10 minutes in, he makes a bench dog with a small piece of wire from a clothes hanger which keeps the bench dog at whatever height you want. Only takes a few minutes to modify an existing dog.
